A Unified Blister and Subglacial Hydrology Framework for Supraglacial Lake Drainage Events
Hanwen Zhang, Laura A. Stevens, Ian J. Hewitt +1
Subglacial blisters form due to the rapid drainage of supraglacial lakes into grounded ice sheets, and are characterised by elastic ice uplift and transient ice-velocity anomalies.…

Viscoelastic mechanics of tidally induced lake drainage in the Amery grounding zone
Hanwen Zhang, Richard F. Katz, Laura A. Stevens
Drainage of supraglacial lakes to the ice-sheet bed can occur when a hydrofracture propagates downward, driven by the weight of the water in the lake. For supraglacial lakes in the…

Magmatic channelisation by reactive and shear-driven instabilities at mid-ocean ridges: a combined analysis
David W. Rees Jones, Hanwen Zhang, Richard F. Katz
It is generally accepted that melt extraction from the mantle at mid-ocean ridges (MORs) is concentrated in narrow regions of elevated melt fraction called channels. Two feedback m…
